Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/bb1ff6ae23813a01f053dbc64ccf032b8a4c4025 (Implement bindImageTexture for webgl2-compute). If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

It's not possible that this regression is caused by my change. There are below reasons: 1. Currently, webgl2-compute context is only enabled for passthrough command decoder. The context creation will fail if it's a validating command decoder(See https://chromium-review.googlesource.com/c/chromium/src/+/1149711). All APIs of webgl2-compute are also only supported for passthrough cmd decoder. But the crash happens in validating command decoder. So it's not possible that my change caused this regression. 2. The crash is a buffer CHECK failure. My code has nothing to do with the buffer.
